Web1 Jun 2024 · On the other hand, edge states in a hexagonal array of helical waveguides are responsible for the photonic “topological insulation,” in which light that propagates along the edges of a photonic structure is topologically protected from the scattering on defects (Rechtsman et al. 2013; Lumer et al. 2013). WebThe strong coupling equation of three waveguides is dealt with Laplace transform and LU decomposition. The general field evolution equation is obtained by inversion of the …

Web6 Jun 2024 · We study optical Bloch oscillations in the one- and two-dimensional arrays of helical waveguides with transverse refractive index gradient. Longitudinal rotation of waveguides may lead to notable variations of the width of the band of quasi-energies and even its complete collapse for certain radii of the helix. This drastically affects the … Web25 Jul 2005 · This website requires cookies, and the limited processing of your personal data in order to function.
